18 Claims. 1

This invention relates to automatic electric laccounting machines, and Vmore particularly to l lates to a machine designed to accumulate totals from perforated record cards, reproduce major and minor totals on one or more total cards, checksuch total cards against the source totals, and thereafter y optionally or both, collate the total cards so reproduced and checked with the perforated record cards from which the detail data was derived, or direct the total cards into a separate receiving hopper.

In general, the machine consists of a punched card reading and analyzing station, a total card punching and checking station, and means interrelating the two stations for feeding the cards so that total cards may be collated with detail cards. An alternative control provides for the punching and checking of multiple total cards with collating feed of onejset of total cards with the detail cards and the deliveryof another set of'total cards into a total card hopper.

Accordingly there is provided Va detail card feeding and sensing unit which includes a hopper in which perforated detail record cards are placed and from which such cards are fed one at a time througha pair of card sensing assemblies, each consisting of card sensing brushes and a contact roll. A common clutch controls the operation of the detail card feeding and sensing mechanism. One of the two card sensing assemblies at the detail card feeding station controls the operation of accumulators into which detail data from the perforated cards passing through the sensing -assembly is accumulated, and the two sensing assemblies togetherA provide for auto control in the reproduction of major and minor totals in the total cards.- V

There is also provided a card feeding and reproducing station which includes a hopper in which either blank or partially punched cards, preferably diiering in color from the detail cards, are .disposed and from which they are fed periodically into a totalreproducing device which is hereinl illustrated as a cardpunching mechanism. The total card feeding device also includes a card sensing assembly through which punched total cards pass and in which they are checked p for accuracy by comparing the totals punched therein with the totals recorded in the accumulators. Provision is made in the control system for reproducing, as by punching, either a single total card showing either a major or minor total and for the checking of such card, or for the reproducing of a plurality of major or minor total cards and the checking thereof. The card feeding mechanism, the reproducing mechanism and the checking mechanism of the total card feeding unit is under clutch control so that total cards may be fed therethrough while cardsfrom the detail card feed are passing through the detail card sensing unit, whereby the total cards are collated with the detail cards without substantial loss of operating speed.

From the detail card feeding and sensing unit the detail cards are fed through continuously operating feed rollers into a detail card receiving hopper. From the total card punching and checking unit, the total cards are fed along a delivery path between continuously running feed rollers, so that such cards may be fed into receiving hoppers. Along the path of the total card feed are a plurality of delivery hopper selecting blades by means of which the total cards may be either collated with the detail cards, or if two total cards are reproduced at each reproducing operation, one total card may be collated with the detail cards in the detail card receiving hopper, and a second total card may be delivered to a total card hopper. A reject hopper is provided for receiving cards on which the totals may have been inaccurately reproduced, the delivery of such erroneous total cards into the reject hopper being under control of the card hopper selection blades in the delivery path oi' total cards.

I-t is accordingly the principal object of the invention to provide a machine capable of sensing and accumulating totals from perforated record cards and for reproducing total cards showing either major or minor totals, and for thereafter collating the total cards with the detail cards.

Itis a further object of the invention to provide in such machine means for checking total cards against information accumulating devices, and for discharging inaccurately reproduced total cards to a reject hopper.

Itis a further object of the invention to provide a machine in which a plurality of total cards, showing either major or minor totals, may be reproduced and one in which one set of total cards may be collated with detail cards from which the information has been derived and wherein a second set of total cards may be delivered to a separate total card hopper.

It is a further object of the invention to provide for the checking of total cards by subtracting the amounts punched in total cards from accumulators in such manner as to reset the accumulators as a result of the checking operation.

It is furthermore an object of the invention to provide an alternative control wherein a plurality of total cards may be checked by comparing the totals therein against amounts set up in accumulators without disturbing such accumulator totals.

Further objects, advantages and uses of the machine will appear as the detailed description proceeds and is read in light of the drawings forming a part of the application in which drawings:

Fig. 8 is the cam chart.

The machine consists of primarily two units, a punched card reading and analyzing unit and a total card punching and checking unit so arranged that punched total cards may be disposed with detail cards or may be directed to a separate card receiving hopper.

Referring to Fig. 1, the card reading and analyzing unit consists of a supply hopper 2| from which perforated record cards 22 are fed one at a time by a card feed knife 23 to and into a first set of feed rolls 24. Ilhence the cards are fed between a set of sensing brushes 25 and a contact roll 26 to an advance sensing station to and into second and third sets of feed rolls 21 and 28. The cards are then fed between a second set of sensing brushes 29 and an associated contact roll 30 of the second sensing station. From this point the cards are fed to and into clutch controlled feed rollers 28a and then into the first pair of a plurality of feed rolls 3|. The feed rolls 3| carry the cards onto further feed rolls which deliver the cards to a card receiving hopper 32. The card feed knife 23, the feed rolls 24, 21, 28, 28a. and the Contact rolls 26, 38 are all under common clutch control and the feed rolls 3| are continually running.

The card punching and checking unit consists of a card supply hopper 33 from which cards 34, preferably differing in color from the perforated detail cards 22, are fed by a card feed knife 35 to and into a set of feed rolls 35. The cards are then fed by means of the feed rolls v36 through va die and stripper of a card punch to a succeeding set of feed rolls 31. The feed rolls 31 feed the cards to a further se't of feed rolls 38, and the feed rolls 38 advance the cards between a set of sensing brushes 39 and an associated contact chute blades 44 and 45, see also Fig. 3, the leading edge of each resting on a guide surface of armatures 46 and 41 respectively which, in turn. are operated by their respective magnets 48 and 49. The armatures are so arranged that the energization of the magnet 48 will attract its associated armature 46 and lower the leading edge of the chute blade 44. The energization of the magnet 49 will attract its armature 41 and lower the leading edge of the chute blade 45 and at the same time the armature 41, because of its overlapping contact with the armature 46, will push the armature 46 down and lower the leading edge of the chute blade 44.

The chute blade 44 is secured at its opposite edge to a triangular bracket 5|] (Fig. 1A) which is secured to a partition 5| between the receiving hoppers 32 and 42. The chute blade 45 has its opposite edge secured to a triangular bracket 52 mounted on a partition 53 between the receiving hoppers 42 and 43. Thus, if neither of the magnets 48 and 49 are energized, the cards will be guided under both chute blades 44 and 45 and they will be fed to the receiving hopper 32. If the pocket selection magnet 48 is energized, the chute blade 44 will be lowered and the cards will be guided between the chute blades 44 and 45 and into the receiving hopper 42, If the magnet 49 is energized, both the chute blades 44 and 45 will be lowered and the cards will be guided over the chute blades 44 and 45 and into the receiving hopper 43.

The drive for the various units is best shown in Figs. 2 and 4. A motor 55 drives a pulley 51 by means of a connecting belt 56. The pulley 51 is secured to a shaft 58 to which is also secured a ,gear 59. The gear 59 meshes with a gear 6U which has secured to it a gear 6| and is rotatably mounted on a stud shaft 62. The gear 6| meshes with a gear 63 rotatably mounted on a shaft 64. Secured to the gear 63 is a gear 65 which is in mesh with a gear 66, the latter being rotatably mounted on a stud shaft 61. Gear 66 in turn meshes with a gear 68 which is rotatably mounted on a stud shaft 69. The gear 68 meshes with a gear 10 which is rotatably mounted on a shaft 1|. Gear 66 also meshes with a gear 12 which is secured to a shaft 13 to which is also secured a miter gear 14. The miter gear 14 meshes with a miter gear 15 secured to a shaft 16. The shaft 16 through worm threads out therein drives worm wheels 11 which .in turn are secured to the feed rolls 3|. Secured to shaft 16 is a second miter gear 18 which meshes with a miter gear 19 secured to a shaft 80. The shaft through worm threads cut therein drives worm wheels 8|, 82 and 83. The worm wheels 8| drive the feed rolls 4|, the worm wheel 82 drives the contact roll 40 and` the` worm wheel 83 through a flexible coupling drivesvthe feed rolls 38.

Attached to the-gear 10 is a clutch disc 86 having therein a notch 81. Cooperating with the notch 81 is a pawl 88l mounted by means of a pivot 89 on an arm 90 which is attached to the shaft 1|. One-endof the pawl 88is engagedby an armature latch 9 I f pivoted at 92 and the other end of the pawl has formed therein an extension 93 adapted to fall into the notch 81. A spring 94 normally holds the armature latch 9| into engagement with the pawl 88. When an associated magnet 95 is energized, the latch is moved away fromthe pawl, and the extension 93 engages in the notch 81 thus connecting the gear 10 with the shaft 1|.

The feed knives 23 are driven by an eccentric mounted on the shaft 1| in the same manner as decribed in Clair D. Lake, U. S. Patent No. 2,032,805.

There-is also secured to the shaft 1| a gear 96 meshed with a gear 91 which is secured to the upper roll of the pair of feed rolls 24. A pair lof gears 98 are secured to the feed rolls 24 and effect positive drive of both feed rolls. A third gear 99 intermediate the gears 91 and 98 is secured to the top feed roll 24 and meshes with an idler gear |00. Meshed with the idler gear is a gear |0| secured to the top feed roller of the pair of feed rolls 21. The top and bottom feed rolls 21 are positively driven by means of 'gears |02 secured to the feed rolls 21. The contact roll 26 has a gear `|04 secured to it and is driven by means of an idler gear |03 meshing with the upper gear |02 and a gear |04.

Gear |00 also meshes with a gear |05 which in turn is meshed with a gear |06. The gear |06 in turn meshes with two gears |01 and |08 which are secured to the top feed roll of the pairs of feed rolls 28 and 28a, respectively. The lower feed rolls of each pair-are positively driven by means ofgears |09 and ||0 of each pair of feed rolls. The contact roll 30 has a gear secured to it and is driven by means of an idler gear ||2 meshing with the upper gear I0 and the gear It can now be understood how the feeding of cards from the supply hopper 2| is under clutch control to and through the second card reading station, and after the cards have passed through the second reading station the feeding of the cards is no longer under clutch control but they will continue without interruption to the card receiving hopper 32.

Meshed with the gear 96 is a gear 84 attached to shaft 85. Mounted on shaft 85 are the various contact operating cams F. C.

The drive for the first two sets of feed rolls 36 and 31 and the punch operating bail are simiiar'to that described in U. s. Patent No. 2,032,805 issued to C. D. Lake, and therefore will be described only briefly here. Attached to the gear 63 is a notched disc ||3. Secured to shaft 64 is an arm ||4 to which is pivoted a pawl ||5 having an extension ||6 located near its outer end. A spring ||1 tends to engage the extension ||6 with the notch of disc ||3 but is restrained from so doing by a latch arm ||8. The latch arm ||9 is pivoted at ||9 and is actuated by the energization of magnet coils |20. Upon energzation of the magnet coils |20 the extension I6 of pawl will engage the notch of disc ||3 and 'thus couple the shaft 64 with the gear 63.

' Reciprocating motion is imparted to the feed knives 35 by means of a complemented pair of cams |2| and |22 (Fig. 4) secured to the shaft 64. The cams' coact with cam follower |23 securedtoashaftl24.

Alsosecud' to the shaft 64 is a second pair of' complemented cams |25 andy |28. A pair of cam followers y|21mou'nted on one end of a bell "crank |28 pivoted at |29 coacts with the cams 6 |25 and |26 and causes the bell crank |28 Ytobe rotated clockwise a short distance from the position shown in Fig. 4 and then counterclockwise to the position shown. At the opposite end of the bell'crank |28 is a roller |30 which coacts withone end of apawl |3|.

Secured to the gear 59 is a roller |32 which engages the slotted section |33 of a Geneva cross |34. 'I'he Geneva cross |34 is rotatably mounted on a shaft |35 and has secured to it a notched disc |36. Clamped to the shaft |35 is a member |31 to which is pivoted the pawl |3|. The pawl |3| has an extension |39 which is biased by a spring |40 to engage with the notch in the disc |36 but is held therefrom by the roller |30 when the bell crank |28 is in the position shown. When the bell crank |28 is moved clockwise, as previously explained, the extension |39 engages the notch in the disc |36 and thus couples the Geneva cross with the shaft |35. Secured to the shaft |35 is a gear |4| which is meshed with a gear |42 and |43, these gears being secured to the upper rolls of the feed rolls 38 and 31 respectively. Also secured to the feed rolls 36 and 31 are gears |44 and |45 which serve to positively drive the pairs of feed rolls. It has now been described how the first two pairs of feed rolls and the card feed knife, in the punch unit, are under clutch control and the remainder of the mechanism is continually running.

As previously described the feed rolls 38 are continuously driven by the gear 83. The gear 83 is yieldably coupled to the feed roll 38 in order to permit the card, which is being intermittently fed past the punch stations, to be fed into the continuously running feed rolls. The hub of the gear 83 has a cut-out portion |46 in which a pin |41 secured to the shaft 38 is located. A spring |48 is coupled between the pin |41 and a pin |49 secured to the hub of the gear 83, and the spring holds the pin |41 in engagement with the surface |50 of the cut-out section |46.

The punch cam shaft and the continuously running cam shaft, which also serves to drive the counter plates, is driven as follows. A gear |5| rotatably mounted on a stud |52 meshes with the gear 68. Also meshed with the gear |5|' is a gear |53 secured to a shaft |53a on which are mounted the several (continuously running) cams C. C. and the accumulatorV plate drive gears. A gear |54 which is rotatably mounted on a shaft |55 is also meshed with the gear |5|. Secured t0 the gear |54 is a disc |56 in which is formed a notch |51. Cooperating with the notch |51 is a pawl |58 kmounted at |59 on an arm |60 attached to the shaft |55. An extension |6| on the pawl |58 is held from engaging the notch |51 by a magnet arm |62. Energization of a magnet |63 will cause the arm |62 to release the pawl |58 and permit it to engage the notch |51 of the disc |56 and thus rotate the shaft |55.

The punching mechanism is of conventional structure and it includes a rock shaft |15 (Fig. 1) to which is fixed a pair of arms |16 intermediate the side frames. Between the arms |16 and a punch operating bail |11 there is provided an adjustable turnbuckle connection. A threaded rod |18 is pivoted at |19 on the arm |16, and another rod is pivoted at |8|` on the bail |11, both rods being connected by a double ended bolt |82 which is adjustable to vary the position of the bail.

The bail |11 is pivoted on studs |83 in the main side frames and carries a punch actuating bar |84 which is adapted to cooperate with notches |85 anyof .a plurality of'selected interposer pawls |86. Each of thepunchzplungers |86 hasaninterposer pawl 86 whichiis pivotally Vconnected thereto Vby a pin 181.1 Normally the pawl is held out of the path of' the bar v`|8||| and the plunger is held above. thedie by :aspring |88 attached to the. paWl. However, when a punch magnet .PM is energized, the associated .pawl is drawn into cooperation with `the bar |84 and the relatedvplunger is depressed to perforate the card.

An armature |89 ofthe punch controlling magnet PM is mounted on a lever |90 by means of a pivotv |9|. The `lower end of lever |90 .is pivotally connected to a call wire |92, the other end ofv which is pivoted at |93 on the pawl |86. A plurality of such 'connections are made, one to each pawl, the punch magnets PM being Varranged in staggered vrows and columns. .Magnet brackets 20| carry .the magnets of one row as a unit, and have arms 202 which hold ran .insulation bar 203 suspended above the. magnets 'to actas a terminal bar. A number of such units may be ydropped into the .frame and conected by call wires |92.

When attracted, the armature |89 swings the lever |90 in a counter-clockwise direction, and draws the wire |92 to the right, urging. the pawl |86 into cooperation with the bar |84. The pawls |86 are Valigned by slots in a plate r|795 fastened on `a supporting bar |96, the plate being used also to secure one end of the springs |88. vThe edge of vthe bar |96 cooperates with a cam face on the pawls |86 to hold the selected pawls into cooperation with the bar |84 as the bar is lowered.

An extension |91 on a fixed bar |98'cooperates with the upper ends of the pawls to cam them in a counterclockwise direction out of engagement with .the ascending bar |84 on the return stroke of .the ball. In order to positively hold thepawls in disengaged position, the end of bar |84 cooperates with Ja cam face on each pawl. There is a limit to the downward motion of the plungers |86 becauseof the presence of a fixed bar |99 which projects .into notches 200 cut in the side lof the plungers |86. The .plungers are guided above the holes in the die |61 by sliding in the `stripper' plate 6'6.

The operation of punching is timed to occur during the pause in card feeding when the Geneva wheel .|34 is not in action. As the bail and bar 84 .are reciprocated, any of theypawls may be moved over by the call wires until notches :|85 engage the end of bar |84. Then the connected pawls and Yplungers are depressed to perforate the card and quickly withdraw therefrom to permit the feeding of the card to continue to the next index position.

The accumulators used herein are disclosed in U. CS. Patent No. .2,328,653 to C. D. Lake and W. Pfaff.

Circuit description Upon closure ofthe main line switch yS, power willbe applied to the lines l200 and 20| and the drive motor'55 will operate.

Assumin'gnow that the supply-hoppers 2=| and 33 have cards in them, the hopper 21 having detail cards in it and the hopper 33 vhaving blank 'cards or partially punched cards in it, the punch magazine card lever P. M. C. L. (Fig. 7B) and -the read magazine card lever R. M.C. L contacts-will be closed and their associated relays Rf|3 and 4lib-I4 will be energized.

Punch cardjeed controlV Upon depressingthe start key `and closing the startkey contact (Fig. 7A) a circuit is completed 8 through the R-I relay closing its R|a, R-lb, R-Ic, AR411, R-le points. -Closure of the contact R-'Ia completes a hold circuit for the R-l relay as, follows: from the line 200, through the contacts R-Ia and R-l-la, which are 'in parallel, through the R-la contact, now closed, through the R-I relay coil to the line 20|. vThe iirst time -cam contact CC-l closes following the energization of the R-i relay, the relay R-2 will be energized through the following circuit: from the line 200, through thenormally closed vstop key contact, through the now closed R|3a and R|4a contacts (or R-Ic contact), through the normally closed R|9a contact, cam contact CC'|, the R-lb contact, the vcoil of the relay R-2 and to the line 20|. Energization of the relay R-2 causes its .contacts R-Za, lib-2b and R-Zc to close. Closure of the contact R-2a completes a hold circuit for .the R-2 relay las follows: from the line 200, through the normally closed stop key contact, through the contacts R-l 3a, R-l4a, or R-Ic, now closed, the contact R-|19a, contact R-2a. now

closed, through thecoil of the relay R-2, and to the line 20|.

The rst time cam contact CC-2 closes after the energization of the relay R-Z a circuit will be completed through the punch unit clutch coils |120 and |63 asfollows: Line 200, through the now closed cam contact lCC-2, the contact R-Zb now closed, the contact R-ld now closed, through the normally closed points of the contacts Pif-Hb, through the clutch magnet coils |20 and |63, and to the line 20 Energization of the clutch magnet |20 initiates vcard feeding inthe punch unit and therenergization ofclutch vmagnet |63 causes the punch cam shaft to be rotated, thereby-operating the punch cams.

A card is now fedfrom the bottomof the stack 34 in the hopper 33 (Fig. -1) and yby contact with :the punch die card lever causes the associated contact to close and energize the relay R|5 as follows: Line 200, through the now closed P. D. C. L. contact (Fig. 7B), the coil of the relay R-15, and `to the line 20|. Energization of the relay R-|5 opens its R-I 5a contact-and transfers its R|5b contact. The transferring of the R-I-Sb contact (Fig. 7A) opens the circuit to the vpunch clutch magnets `|20 and |63, thus permitting the punch clutches yto latch up at the end of the cycle.

The circuit just described has caused a card to be fed from the supply hopper 33 to the punch station ready to have information punched in it the next time the punch clutch magnets |20 and 6'3-are energized.

When a circuit is completed through the punch clutch coils |20 and |63, by the closure of CC-Z, a circuit is valso completed through the read unit clutch coil l and the relay R-3 as follows: Line 200, cam contact CC-2, R-2b, R-Ie, through the normally closed pointsof R-Hb, through the rnormally closed contacts R-3-2a, through the clutch coil 95 and the relay coil R-3 and to the line .20l. Energization of the relay R-3 causes closure of its R3a` contact which completes a holding circuit for theclutch magnet coil .and the relay R3 as follows: Line 200, through the R-Zc contact, now closed, .through the normally closed R-32b contact, through the now closed R-3a contact through the R-3 relay coil and the clutch Vmagnet coil 95. and .to the line 20|.

v'The circuit just described causes a perforated record card to vbe fed from the bottom 'of the stack 22 vin the detail card hopper 2|, to the first sensing station,'i. e. to contact roll 26 and the associated sensing brushes 25. Near the end of this cycle the relay R|6 is energized by the closure of RCL #I card lever cont/act.

During the next cycle the first card is fed from the contact roll 26 and the brushes 25 to the second sensing station in which is located the sensing brushes 29 and the associated contact roll 30. As the card is fed past the first sensing station, a major and minor control break is eiiected (circuits to be described later) and the relay Rw32 is energized, thereby causing the contacts R-32aI and R-32b to open and R-32c to close. Opening of vR.32b opens the holding circuit for the relay R-3 and the clutch magnet coil 95. Opening of R-32a prevents a circuit being completed through the R-'3` relay coil and the clutch magnet coil 95 uponvclosure of the CC-2 contact at the yend of the cycle. Just prior to the completion of the detail card feed at the end of the second card feedicycle the RCL'#2 contact is closed and completes a circuit throughthe R-I 1 relay coil, energizing the R|1 relay and thus causing the R-I'la contact to open, the R-Ilb contact to transfer and the lIf-Ilc (R-I1d) contacts to close. Upon opening of contact Rf-I'Ia. the holding circuit for the relay R-I is opened and, providing the start key is not held closed, the relay R| will be deenergized.

Thus upon initial depression of the start key,

which a card is fed to the punching station whereupon the feed is suspended until called into operation for recording a result. At the same time the second feeding cycle feeds cards into the reading unit of the machine such that the first card is at the second sensing station and the second card is at the first sensing station.

The break in control which occurred during the second card feed cycle just explained caused the contact R.32c to close, and near the end of the cycle when the cam contact CC-2 closes a circuit will again be completed through the punch clutch rmagnets |20 and |63 as follows: From the line 200', through the cam contact CC-2, through the'contact R.2b (now closed), through the contact -Rf-32c (now closed), through the contact Rf-30a (now transferred), (relays Rf30 and R-3I are energized by virtue of the major and minor control break and the circuits for energizing them will be describedlater), through the normally closed R,35a contact, through the R-I5b contacts (now transferred), through the punch clutch magnet coilsV |20 and |63, and to the line A punching operation followsV and a new card is fed to the punching station. During the punch cycle the relay R35 is energized upon closure of PCL-3 (Fig. 7D) as follows: Line 200, through PC-3, normally open points of contact R.-30b, pick-up coil of R35 and to the line 20|. A circuit is completed through the holding coil of the relay Rf-35 as follows: Line 200, CF-2 cam contact, R-35b contact (now closed), holding coil of the relay Rf-35, and to the line 20|. Energization of the relay R-35 also opened its vlil-35a points, thus opening the circuit to the punch clutch magnets |20 and |63, thus causing the punch unit to latch up at'the end of the cycle. The card just punched, however, continues to be fed vand is fed past the checking station between the contactroll 40 and the brushes 39. The amounts punched in the cardare checked against the amounts Standing in the counters from which the card was punched. v The checking operation, except when two cards are punched and checked as will be described later, may be accomplished by subtracting from the counter the amount punched in the card and if the amount punched in the card is correct the accumulator will be returned to zero. If the accumulator is not returned to zero, the machine will stop and a suitable indication will be given. The circuits for this operation will be described in detail later. If the punched card is found to be correct the relay R-30 will be deenergized before the end of the checking cycle and when the cam contact CCI-2 closes near the end of the checking cycle the punch clutch magnets |20 and |63 will again be energized via the following circuit: Line 200 (Fig. 7A) cam contact CC-2, R-Zb, R-32c, R-30a (normally closed points), R-3|a, now closed, R-36a and R|5b (now transferred) through the clutch coils |20 and |63 and `to the line 20|. During this punching cycle when the PC-3 contact closes (Fig. 7D) a circuit will be completed through the pick-up coil of the relay R-36 as follows: Line 200, PC-3, R-30b (normally closed points), R-3Ib (now closed), through the pick-up coil of relay R-36, and to the line 20|. A circuit is established through the holding coil of relay R-36 by the closure of its R-36b contact back through the CF-2 cam contact. Energization of the R-36 relay opened the R-36a contact, thus preventing further energization of the punch clutch magnets |20 and |63 until a detail card feeding operation has occurred and a control break is effected.

The major total card, just punched, continues to be fed and is fed past the checking station where the information punched in the card is checked against the information in the accumulator from which the card was punched. During the checking cycle, if the card is found to be punched correctly, the relay R3| is deenergized. Upon deenergization of both relays R-Zlv and R-3l the relay R-32 will be deenergized causing the R-32 relay contacts to return to normal. Near the end of this checking cycle upon closure of CC-2 (Fig. 7A) the detail card feed clutch magnet and relay R-3 will be energized as follows: Line 200, cam contact CC-2, R-2b and R-i 'lb (now transferred), R32a, the clutch magnet coil and the relay coil R-3, and to the line 20|. Energization of relay R-3 closes the R-3a contact and establishes a holding circuit as follows: From the line 200, R-2c, R-32b and R-3a, through clutch magnet coil 95 and the coil of relay R3, and to the line 20|, thus maintaining the detail card feed unit in operation until another control break occurs.

Auto control Provision is made for two classes of auto control, i. e. major and minor auto control, assuming that there are two columns of major control and two columns of minor control the plugging required is as follows: From the two major control field plug hubs 204 (Fig. 7B) to the two left hand plug hubs 201 (Fig. 7C) and from the two minor control field plug hubs 204 to the two right hand plug hubs 201. From the two major control field plug hubs 205 (Fig. 7B) to the two left hand plug hubs 208 and from the two minor control field plug hubs 205 to the two right hand plug hubs 208. Plug connections are made between the plugs hubs 209 directly below contact R-25b (Fig. 7D) and R-Zlb, also between the extra right hand plug hub 209 and the minor plug hub 2|0 and between the lower plug hub 209 directly below the contact R-26b and the major plug hub 2| 0. As the cards are being fed past the first R-23 and yinto the line 20|.

Vand second ysensing stations simultaneously, a hole in the card when presented between the contact roll and columnar brush will complete a circuit through certainof the autou control relays (Rf-2| throughgR-2I), Referring to the units order of the minor control, as the hole inthe units order ofthe control field in the card passing the first sensing station passes the sensing brushes, a

` circuit willk be completed through the relay R-23 through the plug hub 204, through the plug wire,

into the plug hub 201, to the pick-up coilV relay relay R-23 closes its R -23a points and transfers lts R-23b points. Closingl of the R-23a vpoints (Fig. 7D) establishes a holding circuit for the R23 "relay as follows: Line 200, CF-I, R-23a, hold coil of relay R-23 to line 20 I. At the same time, if the 4hole in the units order of the control field in the card passing the first sensing station is in agree- -ment with the corresponding hole of the card passing the second sensing station, a circuit will be -completed through the pick-up coil of the re- -lay R-Zl (Fig` 7C) as follows: Llne'200 (Fig. 7B), vCB-I R-I 1c, into the contact roll 30, through the V hole in the card, through the brushY 29, into the plug hub 205, the plug wire, into the plughub 208 (Fig. 7C), through'the'pick-up coil of the relay R2'I and tothe line 20|.' Energization of the relayR-2'I causes its R-ZIa contacts to close and its R"2'Ib contactsto transfer. Closure of the R'-2'Ia contactscompletes a holding circuit through the holdingy coil of the relay R-2`I similar to the holding circuit for the lrelay R23.

After'CB-I opens, at each indexpointjCB-3 closes and applies a testfpulse to each of the pairs lof contacts H4201), Rf-Zlb, R-Zlb, RL-25b, R-22b, R'-26b, R-23b and R`2 1b. If the data ineach card 40 isvin agreement the ycircuits] through these contacts will be maintained open.' If however, the datarshould noty be in` agreement in any one or "7 hole punched in it. When yi the "9 hole is sensed at the second sensinglstation, the relay R-2'I will be energized and the R421?) contacts will be trans- .ferred. `Atf9.5 when --the' CB-3 contactlcloses, a circuit will be completed through the pick-up of Arelay lit-28 asfollows: Line 200, CB-3, R-23b (normally closedv points), Rl-2lb (now trans- Lferred), plug hub209',.plug wire, minor plug hub 2I0pickeup coil R-28 relay,V to line 20|; VEner- A'Vl'gization of` the relay lft-28v causes its associated contacts Etf-28a,t Pt-28h to close. Closure' of .Y R-28a completes a-crcuit through the R-28 relay holding coil as follows: Line 200, cam Contact 'CC-9, vR'28 i,-R-28 vholding coil,v and to the line 20|. Closure of contact R28b establishes a circuit which will be completed upon closure of the cam contact CC- I as follows: Line 200, cam con-` tact CC-|0,- R`2 8b, R-30 pick-up coil, and to the line' 20|. fers itscontacts R30ct and R930?) previously de- Energization of the relay R-30 transscribed.Y It also closesits contact R-30c, transfers its contacts R-30cl,` R-30e, R-3 0f, and R-30g,

Closure of R-30c contact completes a circuit through the R-'30 holding coil as follows: Line 200, R-Ia, R-a, Rf'-30c, -R-30 holding coil, and to the line 5 20|. The relayR-30 will remain energized until the latter part ofthe checking cycle, if the data punched in the card is found to be correct. If, however, thedata punched in the card is found to be in error the relay R-30 will remain energized until the operator manually depresses the error reset key `which resets the accumulators from which the. card, found to be in error, had been punched. If `the control change occurs in the major con- 15 trol data eld, a circuit will be completed through the R-29 relay pick-up coil upon closure of CB-3 Y through the llt-2|?) and R-25b contacts or the liz-h. and R'-24b contacts, or both. The relay TR1-29. establishes a holding circuit through its 2()A holding coil throughV closure of the R-29a contacts.; Energization of the relay R-29 also causes v energization of the relays R-3I and R-30 through closure of the Ri-29b', R;.-29c contacts when Vcam Y contact CCi-I 0 closes. When a major control break occurs two total card punch. cycles and related checking cycles ensue. .The rstpunch cycle records the minor total data and thesecond lpunch cycle records the major total data. During the checking cycle of 30'the1 minor total. data the relay R-30 Will drop out if the punched data is found to be correct. If the punched data is found to be in error, the related relayvR--30 orR'3I will remain energized `untilithe operator depresses the error reset key. Energization of'either of the relays will cause energization of the relay R-32 by the closure of veither of the contacts R-30h" or R-3Ih and relay R-32' will remain energizedA as long as either of the contacts areclo'sed.

.Accumulator entry To effect` entry into-the accumulators, it is necessary to plug connect lthe accumulators to the -F second sensing stationaccordingly` To make an entry into accumulator #I (Fig. 7B) it is neces- -sary to plug vconnectfrom the accumulator -plug hub. 2I| to thev second sensing station plug hub 1205. Assuming a 5 hole inthe units column, the circuit effective for entering a 5 into units Aorder of the accumulator is as follows: Line 200, Vv'CB-I (at 5 time), Ri|`|c (now closed), contact f roll' 30, brush 29, plug hub' 205, plug wire, plug Vhub 2II (units order); Ylit-3912 (normally closed),

carry control contacts A (now closed), accurmulator add magnetlunits order),'and to the .fline20|.,i1Energization of the accumulator add magnet causes the accumulator clutch to engage atv 5.and rotate the accumulatorwheel. At the t Omachineftime the accumulator clutch is me- 60. chanically disengaged and the accumulator Wheel `willcome to rest with a- 5 entered into it.

.Carry circuit If an order has passed from- 9 to 0 in the Lake et al. Patent No. 2,328,653 it is necessary to effect a carry (add l) to the next higher order. 'If thiscondition has occurred in an order, its carrycontacts l0 are closed. At the carry time in the machine cycle the carry control contacts "B are closed and A are open. When CB-2 closes at the carry time a circuit is completed through the add magnet of the next higher order (assuming units order accumulator #I went through 9" to 0), as follows:. Line 200, C13-2,

accumulator carry contact 10, carry control that the unitsorder went through 9 as just explained and the tens order stopped at 9 then the' unitsorder accumulatorcarry contacts would be clo'sed on the 10s side and the tens order accumulator carry contact would be closed on the 9s side. The carry pulse through the tens order will be as previously described. The carry pulse through the hundreds order will be the same as for the tens order up to the tens order add magnet where a rcircuit then branches off through the tens order accumulator carry contacts on the 9s side, through the hundreds order carry control contacts B through the hundreds order accumulator add magnet to line 20 Total card punching .(minor readout control), from plug hub 2|l| (minor rreadout control) to plug hub 2|5. Also from plug 2I2l accumulator #2 to plug hub 2|3 (major readout control), from plug hub 2|4 (major readout control) to plug hub 2|5.

Assuming that a major control break occurs, the relays R-30, R-3I and R-32 (Fig. 7D) will be energized asfpreviously' explained. A punch cycle is initiated and upon closure of PC-2 the relay R-33 will beV energized in the following manner: Line 200, PC-2, Rf-30d (now transferred), R-33 coil, to line 20 I. Energization of relay Rf33 closes its contacts llt-33a,v R-33b, R33c,v and R-33d (Fig. 7C). Closure of these contacts condition circuits to the punch magnets which will be completed upon closure of PCB-I. During the second punch cycle the relay R-34 (Fig. 7D) is energized as follows: Line 200, PC2,` R-30d (normally closed points),'R-3|d, R-34 relay coil, to line 20|. Energization of relay R-34 closes its contacts R-34a, R-34b, R34c,`and R-34d (Fig. 7C). Closure of these contacts conditions circuits to the punch magnet vwhich will be completed upon closureof PCB-I. A typical'circuit would be as follows: Assuming that there is a in units order of accumulator#|, then at the 5 to the punch magnets which will be completed follows: Line 200, PCB-I, readout emitter 5 segment, units order accumulator readout 5 segments, units .order accumulator readout common, plug hub 2|2, plug wire, plug hub 2|3, R-33a, plug hub`2l4, plug wire, plug hub 2|5, to the punch magnet coil, and to the v'line 20|.

Multiple total card punching AIt is sometimes desirable to punch a pluralityA punched and 230 causes two cardsto'be punched) If it is desired to punch one card for each class 14 of control break. the plug hubs 231 and 239 are `both plugged to plug hub 236. If two cards are to be punched then the plug hubs 231 and 239 are both plugged to the plug hub 238. One typical example of such an operation is to punch one total card for each minor control break and two total cards for each major control break. In order to have the machine function in this manner at the respective control breaks, it is necessary to plug connect plug hub 236 to 231 land 238 to 239. During the checking cycle which follows each punching cycle the relay R-I 8 is energized and its contacts R-Ie, R|8d, R|8e, R-Isf, Rf|8g are closed. If two cards are to be punched, the first card punched will close the CCL contact at a half point before D (see timing chart) and contact will remain closed until the second card has passed the checking station and then the CCL contact will open at the 18th point of the cycle. If the card just punched (i. e., the minor total card) is found to be correct, the relay R|9 will not be energized (checking for multiple cards to be described later) and upon closure of the cam contact CC-IB a circuit is completed through the advancing coil of the stepping relay #2 as follows: Line 200 (Fig. 7E),

Vthe cam contact CC-IS, R-lf, R-Iilf advancing coil, and to the line 20|. Shortly after the cam contact CC-IB opens, the cam contact CC-20 closes and a circuit will be completed through the R42 relay coil as follows: Line 200, the cam contact CC-2 0, R-Ig, stepping relay! #2, bank #L first point, plug hub 236, plug wire, plug hub 231, R-30n (now transferred), coil ofrelay R42, and to the line 20|. Energization of relay R42 `closes its R42a point and opens its R422), R420 points. Closure of R42a completes a holding circuit for the relay R42 as lfollows: Line 200, R-I 0e (now closed), R42a, the coil of relay R42, and to the line 20|. The opening of R42c (Fig. '1D-1) permits the dropping out of the relay R-30 upon opening of the cam contact CC-I When the relays R-30, R-3-|v are energized, the

condensers 240 and 242 (Fig. rIE) 'are discharged through the resistors 24| and 243 respectively by the transferring of the contacts R-30m, R-3|m, respectively. Now upon the dropping out of the relay R40, the contact R30m is returned to normal and the relay R43 is energized momentarily by the charging current of the condenser 240.' The momentary energization of the relay R43 closes its R43a, R43b points. Closure of the R431) points completes a circuit through the reset coil of the stepping relay .#2 thus resetting the stepping relay. If two cards are fed consecutively, R|8 will stay picked up because `the card contact will overlap the second card.

If only one card is being fed, it holds for one cycle and then drops out. At the completion of the checking cycle, after the cardleaves the checking station, card contactv CCL opens causing relayR-l to deenergize. Deenergization of 'relay R|0 accordingly opens Rle contact yand thus opens the holding' circuit for relay R42, permtting it to drop out. Following the checking of ther'ninor total punched card, a punching cycle is again initiated in which the 'major total data is punched in the card and then checked. During this cycle if the punched data is found to be correct, a circuit is completed through the advancing coil of stepping relay #2 as previously described, advancing the stepping relay contacts to their first contact position. Upon closure of the cam contact CC-20, this time, there is 'no circuit completed because the contact R-30n has been returned to normal position. Thus the recuit for theR-G relay as follows: Line 200, CC-S vR'-6a, RAS holding coil, and to the line 20|. YClosure of R-Gb contact completes a circuit .through the R-T relay coil and the R-I relay lay R-.3l is prevented from dropping out .when

.the cam contact CC-i 2 opens by the closed shunting Vcontacts R-lZb and R-Sb; accordingly, at the end of the checkingcycle the relay contact R-3 la is still closed. The contact R-36ais closed bythe opening of theft-36 relay holding circuit at the beginning of the checking cycle, and upon closure ofthe cam contact CC-2 the punch clutch magnetsA |20 and |63 are again energized and a second major total card is punched and checked. During the second checking cycle, up-

lon closure of the cam contact CC|9 the .advanc- .ingr coil ofv stepping relay #2v is again energized advancing lthe stepping relay contacts to their ysecond contact position. This time upon closure vof the cam contact VCC-20 a circuit is completed through thevcoil of relay R-42 as follows: Line 200, cam vcontact CC-20, R-Iag, stepping relay #2, bank #L second contact position, plug hub 230, plug wire, plug hub 239, R-3 in (now closed), R-30n A (normally closed), -R-42 .coil, and to the linef20l. The holding circuit is established for the relayR-Z through R-I8e and R-42a contacts as previously described.- Now upon the openingA of the cam contact CC-IZ the contacts `Rf-'Mband R-307c, are all open and the holding Vcircuitfor the relay R,-3| isopened, thus permitting the Vrelay to drop out.

Checking of total card punching Each punching operation f is followed by a checking cycle inwhich the card `iust punched is checked against the accumulator from which it was punched. The checking of single total cards may be effected by subtracting the amounts lpunched inthe card from theA accumulators from vwhich thecard'was punched. VIf the ca rd was punched correctly the accumulator will be restored rto zero setting.

to plug hub 222, plug hub 223 to plug hub 224 (Fig. 7A), and plug hub 225 to plug hub 226.

Near the end of the punching cycle the R-E relay is energized by the' closure of the cam contactV PC-I which completes a circuit through the pick-up Ycoil of the relay R-S. 'Energization of the R-S relay closes its R-Ga, R-Gb contacts. Closure of contact R-Sa completes a holding circoil as follows: 'Line 200, R-Sb', R-30f (now trans- Ierred) plug hub 223, plug wire, plug hub 224, coil of R-I and hold coil R-"I relays to line 20|. Energization of the R-I and R|| relays closes their associateda, b, c and d contacts in the accumulator #I circuit (Fig. 7B). At the start of 'the checking cycle, D time, the accumulator add magnets are all energized by the closure of the cam contact CC-7 through the contacts R-la, R-lb, R-7c, and R-Td. As the card is fed past the checking station the differently timed pulses, produced through the holes in the card are directed to the accumulator subtraction magnet,

thusstopping theV rotation of the counter wheels.

and if the holes in the card are in agreement with the amount in the accumulator, the accumulator will now be returned to zero setting.

The circuits for one order will now be described. Assuming that a 7 is recorded in the units order of counter #L then a 7 will be punched in the units order of the related field in the card. As the punched card is fed past the checking station, the accumulator wheel is started rotating at D, which is one point before 9, by the energization ofthe add magnet from line 200, through cam contact CC-T, R-Ta, counter add magnet, and to line 20|. At the 7 time'a circuit will be completed, through the 7" hole punched in the card, through the counter subtraction magnet via the following circuit: Line 200, CB-l, R-lc, contact roll 40, through the hole in the card, brush 39, plug hub 206, plug wire, units order plug hub 236, R-i la, accumulator subtraction magnet, to line 20|. Thus the accumulator wheel which was setting at the "7 position will have been advanced three points and will be declutched at 0 setting.

Shortly after the accumulator entry portion of the checking cycle, the cam contact CC-8 closes to test the accumulator settings and determine if it has been returned to zero or not. If it has been returned to zero the closing of the-cam contact CC-8 will not complete a circuit. If, however, any one of the accumulator positions fails to be returned to zero then a circuit will be completed through the pick-up coil of the relay R|9 (Fig. 7C) upon closure of the cam contact CCI-8 as follows: Assuming that the units order of accumulator #I was not returned to zero, line 200, cam contact CC-8, Rf-I 8d, R-30e (now transferred), plug hub 2|6, plug wire, plug hub 2| 1, readout common (highest order), readout brush to the highest order zero segment, readout common, readout brush, zero segment, readout common, readout brush of the tens order, zero segment of the tens order, readout common of the units order, readout brush of the units order, to one of the digit segments 1-9 inclusive, back to the 1 digit segment, across the 1 digit segments to the hundreds order, down the digit segments of the hundreds order to plug hub 220, plug wire, plug hub 22|, plug wire, plug hub 222, R|9 pick-up coil, to line 20| Energization of the R-I 9 relay closes its contacts R-l 9a, R-I 9b, R-I 9c. Closure of R-I 9a completes a circuit through the R-IS holding coil as follows: Line 200, R-5c, Rf-I9a, R-IS holding coil, and to the line 20| Thus, the relay R|9 will be held energized until the R-5c contact is opened by the energization of the relay R-S, to be described later. Closure of the contacts R|9b and R|9c prevents dropping out of the relays R-30, R-3I respectively, once they have been picked up, until after the error reset button'has been operated.

If a card is found to have been punched in error, the machine will stop and the card on the top ofy the stack in the receiving hopper will be the one in error.

Checking of multiple punched total cards Each multiple punching operation is also followed by a checking cycle in which the cards just punched are checked against the accumulator from which it was punched. The checking in this case must be effected by comparing the amount in the counter from which the card was punched with the amount punched in the card, a manner similar to that of comparing the controlling data in adjacent cards passing through the. card feeding and analyzing unit for auto
